Beautiful bartender with his own shop, getting won over by a customer who's the only one seeing his 'other side' - slowing developing relationship because bartender is untrue and lieing regarding his feelings and not quite trusting the intentions of the customer.
Lots of hot, uncensored smex with little to no inhibitions since both are experienced, mature guys knowing what they want - hole stretching and cum dribbling inclusive.
All in all a nice, mostly realistic story with good character and relationship development and a happy end.
Including the sequel blue moon.
